jac_no_k··on MacBook Air M4
I really was hoping for nano-texture on MacBook Air. The cynic in me thinks this is intentional as I'm now purchasing the 14" MBP with nano-texture. It's 42,000 JPY ($282 USD) more then a near equivalent MacBook Air. But the matte display is the killer feature for me.

And this is to finally replace my trusty 2025 MBPr. It's had an extremely good run. May this one also be a ten year laptop.

jac_no_k··on How Nissan and Honda's $60B merger talks collapsed
I would imagine by implying that if Honda doesn't cooperate, they would face increased regulatory scrutiny. IE, Honda factories needs to have more safety inspections, vehicles fails to pass emissions tests, a finding that requires huge recalls, etc.

I hope this is successful but have a feeling that it's going to end up like Premium Friday. https://en.wikipedia.org/wiki/Premium_Friday Starts with big fanfare, supported by businesses, until focus drifts elsewhere and it quietly disappears.
jac_no_k··on Show HN: Stretch My Time Off – An Algorithm to Optimize Your Vacation Days
In Tokyo, Japan where I work, I get a generous number of days off. I was surprised just how long this could be stretched.

- Tokyo 30 days to 83 days.

- Hong Kong 30 days to 77 days.

- California 30 days to 76 days.

- France 30 days to 70 days.

jac_no_k··on Turning AirPods into a fitness tracker
For Garmin watches, auto activity tracking is under Settings > Activity Tracking > Status On. This shows up in Garmin Connect under graphs such as Body Battery, Heart Rate, etc. These auto tagged items don't show up as discreet activities and will not show up in other systems like Strava.

This is on the Forerunner 945 and will auto tag things like walks, runs, and cycling.

jac_no_k··on Toyota patents plans for EV with manual transmission and clutch
Nissan Leaf with it's single pedal setup is like a driving a car in 2nd gear, where the speed can go down to zero and accelerate all the way up to highway speeds.

In single pedal mode, slowing down to a stop is a lifting the accelerator pedal completely and it will come to a stop in predictable manner. The brake pedal adds more regen and stronger application applies the brakes itself. From a stop, pushing down the accelerator starts moving the car. On hills, there is brake assist and works without any drama. Operating in reverse is the same way.

In dual pedal mode, or classic operations. While under motion, lifting the accelerator has a bit of regen until about 7kph and then creeps forward. To come to a complete stop, the brake pedal is necessary. From a stop, lifting the brake pedal starts the creep forward. This being an electric, even on inclines, the creep forward is consistent. Reverse is the same way.

At slow speeds, ie parking, it is easier to have the creep mode. Controlling speed with the brake pedal feels better. However, with experience, single pedal slow speed works well, just have to feather the throttle.

I've set the car to default to two pedal setup on start. I hit the single pedal mode switch every time I'm driving. It works well in a shared car setup. I do find it more weird to now drive with two pedals, but using the brakes still comes up even with single pedal driving, so if I do "forget" which mode I'm in, I'll still use the brakes when the car isn't slowing down enough.

Regarding the simulated legacy behavior, ie rolling back on the hill or changing torque. This is in the same line as simulating gearing in a CVT and simulating engine noise. I don't find it appealing and do hope car manufacturers have it as a configurable item, like Nissan has done with the one pedal driving. Here in a Japan, even the noise generator to warn pedestrians can be turned off.

jac_no_k··on What We Can Learn from Japanese Prefab Homes
I think it depends if the house was pre-built or meant for rentals. I had the unfortunate experience of buying a used pre-built house in the Tokyo area and it was terrible. Every room vented directly outside, windows were single pane with bare framing, and it felt like it had only token insulation. Same with rental apartments, with the only benefit being small places.

The builders I've worked with; Tokyu Homes and Seksui House build all over Japan and have a catalog of options catered for each region. ie: Kanto (Tokyo area), Tohoku (Aomori), Hokkaido, etc. The contents of the catalog are surprisingly different. For example, triple pane glass and heat exchangers for ventilation is not shown in Kanto catalog.

My ex-partner was an architect and I have a strong interest in things mechanical. Along with experience of having multiple homes built for us and with a western attitude, we were able get a livable house that's fairly efficient (for a Western lifestyle).

jac_no_k··on What We Can Learn from Japanese Prefab Homes
I used to live in the southern California area in the United States. I made a bit better then you average salaryman. Home prices varied wildly but I was able to get a 30 year loan for a new construction house. I did benefit from for low interest rate and liberal lending practices.

In Japan, I make nearly double what an average salaryman. This made getting a 35 year mortgage possible. I spend about 30% of my income on the home, its taxes, and upkeep. The current house is customized to higher spec then what is typically offered.

Like many places, prices vary quite a bit. This home was purchased during the "before" times and my commute into central Tokyo was between 90 to 120 minutes, by train or bicycle. Land prices is a quarter of what it is close to the center, about half compared to places within an hours commute time. For location reference, my station is: https://en.wikipedia.org/wiki/Haruhino_Station

The building itself is relatively cheap for the quality. I was able to spec it out before it was constructed. Most pre-built houses do skimp on insulation, ventilation systems, and typically have primitive co-generation power.

The curious thing about Japan is that buildings depreciate to zero in 30 years time. Land prices are stagnant or loses value the further out from major metropolitan areas. I had to get a realtor estimate on the house, and in the four years since the house was constructed, I would only be able to sell for about 80% of what I purchased it for.

jac_no_k··on What We Can Learn from Japanese Prefab Homes
Owner of a customized pre-fab (!?) home here in the Kanto (Tokyo) area.

Homes in Hokkaido area, where it gets quite cold in winter, have good insulation. If one is building a custom house in Japan from construction company that does pre-fab, ask to see the catalog for houses in Hokkaido. It will have features such as double paned windows and venting systems with heat exchangers. I'm the only one in the neighborhood with the heat exchanger setup.

Regarding central air versus having a compressor for each room. My previous house in the same area had central air and in hindsight, it wasn't an economical choice. It made all the rooms drafty and we were constantly fighting with low humidity. The current house has it's own compressor for each room and along with the ventilation provided by the heat exchanger, just running two units downstairs is enough for the whole house.

jac_no_k··on M1 MacBook Air hits 900 GFlops in the browser with Safari's experimental WebGPU
I've been using "Magnet" for tiling. It's in the Apple App store. My use case, 15" laptop display and a 32" 4k display. I find it sufficient enough screen real estate. I sometimes think about getting an additional display but can't quite justify it.
jac_no_k··on How hard should I push myself?
I wish we had better metrics to measure stress. Is it okay to push harder?

From a physical exertion perspective, I think we have it. Recovery Time: https://support.garmin.com/en-US/?faq=8ImmxVkZMh4EYYq5Zp2bR8

From a stress level perspective, I think it exists. Body Battery: https://www.garmin.com/en-US/blog/fitness/5-reasons-your-bod...

It took me multiple visits with a therapist to find that I need to have more self-care, otherwise I fall off a cliff. I need to take care of myself to be able to help others. What that is to be able to recognize symptoms and have techniques for coping with the stressors that have become too much.

I still struggle these days. The metrics from the "Body Battery" and "Stress Levels" let me acknowledge that I've had a bad day and need to rest.

jac_no_k··on Sharrows, the bicycle infrastructure that doesn’t work and nobody wants
Some cyclists get empowered by the "sharrows" and purposely become nuisance to other road users. While the cyclist does have the right of way, the intent is to signal to automobile drivers to share the roads. Courtesy from the cyclist would be to share the road with other road users.

I do find that cycling on roads with "sharrows" have less aggressive behavior from cars.

/me: Cycle commuter for 15 years in Tokyo, 20km to 40km each way during the "before" times. Currently mostly casual group café rides totaling 200km to 300km a week.

jac_no_k··on Wyze $20 Smart Watch
Similar experience on my side. I was sitting on the fence between an Apple Watch and the Garmin 945. I'm quite pleased with the Garmin 945 all day tracking, the ability to track activities for over 12 hours (GPS, routing, and bunch of metrics), and good battery life. While the software ecosystem in Garmin feels a bit rough, it's usable. It's the software that makes it stand apart from these lower priced offerings. Even the Garmin VivoActive has interesting metrics when paired with software Garmin Connect.
jac_no_k··on Bugatti has broken the 300mph barrier
/me commutes by bicycle, 32km each way, in traffic light hell that is Tokyo.

I can get off the line faster then automobiles, they aren't racing / clutch dumping at the lights. Traffic is so heavy and with so many intersections, it's typically pointless for automobiles to race off the line anyways.

As I filter past daily the same Pagani and Bugatti and LFA and Tesla S and NSX. :D

jac_no_k··on Apple Is Listening
Actually, I think Microsoft's effort is putting much needed pressure on Apple. My wife about a year ago got a Microsoft Surface 6, the tablet with keyboard + trackpad. It was about the same price as a MacBook and with a bundle, the Microsoft Office suite came included. It works well for my wife's use case and she's able to stay with her preferred interface.

Hardware has been trouble free, Windows 10 with One Drive makes it straight forward to change machines, apps run well as a normal user account, and to my knowledge it hasn't been hit with any malware. The screen being capable of touch interface, can actually be cleaned!

In comparison, my last of the "good" MBPr from 2015 has a partially fouled screen because the slightly greasy keys touched the screen. I am so annoyed when the screen is dark but I'm in a well lit room.

jac_no_k··on Every Vehicle Should Have an Electric Motor, Even If It Doesn’t Have a Plug
I test drove the Nissan Serena e-power (series hybrid mini-van) and having all the torque available is a killer feature. It won't win any high speed medals but to be able to get up to 50kph (30mph) with no drama is useful. Combines the torque happy electric car with the range capabilities and infrastructure support of ICE.

You see this electric motor pattern in a variety of cars. The current gen Acura NSX has the front wheels driven by the electric motors, rears driven by an ICE engine. The Mitsubishi Outlander comes in a PHEV version, with about 50km of electric only range, switching over to ICE as needed.

While I ended up with the Nissan Leaf (battery electric vehicle, the plug in kind), currently about one year of owner ship, I do miss for long distance, at speed, travel of gasoline cars.

jac_no_k··on Foreign Minister Taro Kono to ask media to switch order of Japanese names
Other "problems" for Japan foreign residents: * I'm of Japanese ethnicity but not Japanese, so must use katakana. Confuses everyone. * My wife, also not Japanese, kept her maiden name; breaking all kinds assumptions on forms. * Recently my wife has taken on Japanese citizenship and now uses the kanji form of my katakana last name. More confusion from various institutions. * My kids did not take on the Japanese citizenship and pretty much stands on school rosters. * And what about the katakana romanization of the names!? My first name has two different variations...

I could go on... but for name ordering problems, my bank credit card allows choices on how the name is to be used on the card. I naively picked FirstName MiddleInitial LastName for the credit card. This does not match any form of Japanese identification. So when I'm trying to buy say a SIM card, inevitably an exception is thrown and some crazy Japanese style escalation ensues.

jac_no_k··on Changes to Models S and X allow them to travel longer without larger batteries
This "continuous deployment" for cars must be a logistical nightmare. To do repairs for a given vehicle, keeping track of what parts are backward compatible would be challenging. What if it's a compatibility breaking change? Then keeping inventory for older cars would become problematic.

Unless they do design with maximum compatibility. Then it gets interesting as upgrades are possible.

While B.EV cars maintenance is low, my car 7 months into ownership revealed bad battery cells that needed replacing. If the car was say five years old, would this replacement have been possible?

jac_no_k··on The drug debate in Japan (2018)
Japan has other surprise drug policies. For example, the prescription drug Adderall is banned because it contains amphetamine. https://jp.usembassy.gov/u-s-citizen-services/doctors/import...

This article is enlightening in Japan's attitude towards these stimulants. But I could go any convenience store and pick up bottles of "genki" (energy) drinks. There doesn't seem to be much regulations and only the occasional news story of people overdosing.

jac_no_k··on Chevy Volt discontinued: Chevrolet's last Volt rolls off the assembly line
Regarding "novice and expert" mode. Default should be novice mode. Extra steps to go into "expert" mode. Examples I could think of: * Launch control (maximum acceleration from a stop.) * Track mode (turn down or disable stability control) * One pedal drive mode. (Nissan Leaf e-pedal or just B-mode for strong regen)

Ah well... It would be interesting to hear more of the reasons behind decisions.

jac_no_k··on Google Docs gets an API for task automation
@cosmie provides a good model for IT organization to quickly bring supportable solutions. The principles behind Agile is to reach across these barriers / towers. These Experts are the product owners / users, the developers, and also includes UX designers, operations team, security team, and capacity team. This is ideal but realistically challenging to pull off.

A given Firm should also be providing a way for Shadow IT project to brought into the light, formally adopted and supported.

jac_no_k··on Google Docs gets an API for task automation
/me is one of the minions from team "Eye of Sauron". However I'm not stuck in this tower.

I'm torn between two worlds. One side applauds the grass roots based solutions and the JFDI attitude. The other side is concerned that these solutions becomes widely used, de facto production, and problems upstream ends up breaking the output. On error, hopefully fails loudly but subtle problems could creep in. If the reports are consumed by other automation, the problem spreads rapidly.

Ideally the IT department would take a step back, assess what the users (you the stakeholder) needs are, and provide the solutions. Better Agile.

Using the successes to drive more development and operations budget is the way to go.

jac_no_k··on Tesla to Buy Energy Storage Firm Maxwell Tech at $4.75 a Share
2018 Nissan Leaf owner here driving with e-pedal, essentially a single pedal driving from movement to complete stop. I've driven from summer conditions down to -10dC (14dF) conditions.

For winter, the car is on squishier winter tires. This confuses the traction control unit enough to cut out regen on full pedal lift off and switch over to caliper brakes, still single pedal. The car still slows and comes to a complete stop, but deceleration is much stronger with regen. I've adapted to no longer fully lift off the pedal, expecting a more gentle deceleration, providing a more consistent stopping distance.

The brake pedal still responds normally and it gets used in surprise situations.

Even at -10dC (14dF), the regen operates similar compared to warmer temps with the Leaf. At -30dC (-22dF) the battery heater supposedly kicks in, but have not taken the car into those kinds of conditions. I would think it's a software update on the Tesla to kick on the battery warmers in colder climates for consistent regen. Or software update to engage the brakes when regen isn't available.

jac_no_k··on The creeping IT apocalypse
I can't find the article any more but I think Toyota has it's engineers build a handful of cars by hand as part of it's kaizen process. This would act as entry point for next the next generation of engineers.
jac_no_k··on Japan Is Giving Away 8M Abandoned Houses
/me is a US citizen with a PR (permanent residency) status in Japan. Spouse has naturalized to a Japan citizen.

My anecdote: without fitting into any of the qualifying categories, I was able to get a PR in Japan after residing in the country for 10 years. The rules have changed and with the right qualifications it's possible to apply for PR with only two years residency (work visa).

Further anecdote: My wife recently got her Japanese citizenship. This was difficult, it took over a year and an intrusive investigation. Like getting top secret clearance. The investigation brought up why I wasn't pursuing Japanese citizenship until they discovered my low level of Japanese skills, and it was no longer an issue.

My entire family here in the greater Tokyo area is doesn't quite fit in with the Japanese. We're a bit loud. We're consumerists. We get quizzical looks when filling in applications. We've broken software that expected only Japanese to use. It has it's negatives but the positives of being different in this mostly homogeneous society has it's advantages.

Yes, my situation is a small minority but with the policy changes, it's one less hurdle for people who want to live in Japan. We are what makes the "society".
